specific Embodiment

[0070] Taking leafy vegetables as an example, the master control unit sends on / off signals to the LED lights according to the preset light cycle and preset dark cycle to control the LED lights on and off; for example, the preset light cycle is set to 16 hours, and the preset dark cycle is 16 hours. Set to 8 hours.

[0071] When the plants to be cultivated are irradiated by light (that is, in the photoperiod), the master control unit controls the opening and closing of the circulating pump according to the preset circulating pump opening time and the preset circulating pump closing time, and the nutrient solution is sent to the plant when the circulating pump is turned on. to the sink; for example, preset circulation pump on time for 20 minutes and preset circulation pump off time for 10 minutes.

[0072] When the plants to be cultivated are irradiated by light, the master control unit collects the carbon dioxide concentration data of the cultivation room through the carbon dio...

Abstract

The invention belongs to the technical field of plant growing box control, and discloses a plant growing box control system and a control method thereof. The plant growing box control system comprises a cultivation chamber and an environment control chamber. The cultivation chamber is provided with a cultivation frame, the bottom of each layer of the cultivation frame is provided with a water groove, and the water groove at each layer is internally provided with a planting plate. The cultivation chamber is internally provided with an in-box temperature and humidity sensor and a carbon dioxide concentration sensor. The environment control chamber is internally provided with a constant temperature and constant humidity machine and a carbon dioxide steel cylinder. A supplying pipeline of the carbon dioxide steel cylinder is provided with a carbon dioxide steel solenoid valve. The top of each layer of the cultivation frame is provided with an LED lamp. The bottom of the cultivation chamber is provided with a nutrient solution water box and a circulating pump. The environment control chamber is internally provided with a general control unit, the in-box temperature and humidity sensor and the carbon dioxide concentration sensor are respectively and electrically connected with the general control unit which is electrically connected with the control end of the carbon dioxide solenoid valve, and the general control unit is used for controlling the operating state of the constant temperature and constant humidity machine, the LED lamps and the circuiting pump.

Description

technical field [0001] The invention belongs to the technical field of plant growth chamber control, and in particular relates to a plant growth chamber control system and a control method thereof. Background technique [0002] At present, plant factories, as a system capable of finely controlling plant growth, have high market value and application prospects. The plant growth box is a specific form of the plant factory. In the plant growth box, environmental factors such as humidity and temperature can be controlled according to the needs of plant growth. However, the existing plant growth box lacks a comprehensive control method and cannot achieve Uniform control of temperature / humidity. Contents of the invention [0003] The object of the present invention is to propose a plant growth chamber control system and a control method thereof. The plant growth chamber control system of the present invention can realize comprehensive control of temperature, humidity, nutrient...
